[jira] Commented: (LOG4NET-13) Allow SMTPAppender to have replacable parameters in Subject

     [ http://issues.apache.org/jira/browse/LOG4NET-13?page=comments#action_59907 ]
     
Nicko Cadell commented on LOG4NET-13:
-------------------------------------

As the SmtpAppender sends a list of buffered events it would need to pick one event to use for pattern replacement. The From and Subject params could be changed to PatternLayout fields. Then any PatternLayout strings can be used to generate the From and Subject from the selected event.

This would be a breaking change for apps that programmatically configure.

> It would be helpful to be able to have parameters that
> are replaced on a per-log event basis on the Subject
> line for the SMTPAppender.
> Example:
> I have multiple web servers running a .NET web service
> and all use log4net. When an error occurs, they use the
> SMTPAppender to notify me. It would be very useful to
> include the host name of the sender in the subject line
> so that I could easily determine which web server had
> an error instead of having to look into the email.
> In thinking more about this it could either be the
> Subject line or the From line that has replacable
> parameters. Perhaps even make it so that these
> properties can use the <layout> tag.
